Circuit Board Inspection

APPLICATION:

A lens designed to inspect circuit boards to look for faulty components without introducing off-axis views

CHALLENGE:

To design and manufacture a lens with very low distortion, a very short working distance, and a large depth of field.

SOLUTION:

Design:An “uncommon” telecentric lens design; regardless of the deviation from the central optical ray, the components imaged on the circuit board remain equally in perspective.

 

Integration::Integrated with a 28.7mm line scan camera provided by the customer.
Testing:While at first the testing of all lenses was done at our customer, it was later found that COI could preform the QA on this lens more efficiently in-house, so all testing and certification eventually was done at COI.
